Can facial and bodily twitching be due to ALS?

Hello doctor,

I am a 37-year-old male weighing 435 lbs. My height is 5 feet 10 inches. I have a severe issue I am dealing with and need help. It has been more than a year since this has started. It began with facial twitching, then moved on to full body twitching, and it began shortly after I got COVID-19. I searched on the web what this could be, and of course, it led me straight to ALS. Now, the descriptions for this disease are very vague, with no timeline, no exact test, just muscle weakness and fasciculations. This has led me down a dark path of mental destruction for the past 20 months. Over the last 90 days, I have had this weird symptom that appeared, which feels like a vibration inside the body, more on the left side, but it feels as if my bones are vibrating. This comes and goes, especially prevalent when I just wake up. I do not exactly know or understand what clinical weakness means. But in your context, I work on my feet ten hours a day, five days a week. I bought grip strength tools that apply 200 lbs of force and can fully close them with my grip on both hands. However, if I hold my phone up for two minutes, I feel my hands begin to cramp up, or my shoulders begin to burn or fatigue. This has been going on for the entire 20 months. I have gone to my PC physicians, and they do blood work and say I do not have anything to worry about but just lose weight, and it drives me nuts. About 100 days ago, I started getting twitching in my mid-abdomen section, it used to come and go but now it is almost happening all day long. I still get random fireworks in my thighs, thumbs, biceps, neck, face, etc. I am extremely depressed and scared that this is an early ALS situation, and I do not know what to do. Do you think this could be that? What should I specifically look for? What can I do to make this better? I am literally losing my mind. After how much time of this do I know that I am in the clear and this is just BFS? Please help.
